Changing the same property of some axis children using subsasgn

6 views (last 30 days)
How to make the following code work in order to change the 'Visible' property of some children plots whose handles are stored in toHide using subsasgn?
f1 = figure;
ax1=axes(f1);
axis(ax1,'tight');
ax1.NextPlot = 'add';
plot(ax1,[1,2],[3,4],'DisplayName','graph 1')
plot(ax1,[1,2],1.5*[3,4],'DisplayName','graph 2')
plot(ax1,[1,2],2*[3,4],'DisplayName','three')
toHide = findobj(ax1,'-regexp','DisplayName','graph');
%% Method 1
toHide(:).Visible = {'off','off'};
%% Method 2
S = substruct('()',{':'},'.','Visible');
toHide(:).Visible = subsasgn( toHide , S , {'off','off'} );

you could use
for nr=1:numel(toHide)
S(1).type='()';
S(1).subs={nr};
S(2).type = '.';
S(2).subs = 'Visible';
toHide = subsasgn( toHide , S , 'off' );
end
if the objects could be indexed directly this would be more easy, but your Method 1 does not work in my matlab

I assume you know that subsasgn is called implicitly whenever you make an assignment statement, as in the following:
[toHide.Visible]=deal('off')

I thought it could be done without the need to use for-loop.

No, it cannot be done solely with subsasgn, with no loops.
